4.2.2 Mounting the Sunny Island using Wall Studs
If the Sunny Island is to be mounted on wall studs, then
use the holes in the wall mounting bracket as shown in the
figures. Ensure that the wall mounting bracket is
positioned at least over one wall stud. Note that the wall
mounting bracket is designed to mount on a single wall
stud or on two wall studs. When mounting to wall studs,
use a minimum of four 0.315 in (8 mm) lag screws with a
minimum length of 2 in (50 mm).
If two or more Sunny Island inverters are to be installed,
mount the inverters on two studs each in order to get
better cooling. Make sure that the wall where you intend
to install the Sunny Island is vertical and can carry the
weight of the Sunny Island (139 Ib, 63 kg) on a
long-term basis.
Otherwise proceed as per the mounting on a stone wall
(see Section 4.2.1 "Mounting the Sunny Island on a Stone Wall", page 34).
Risk of injury due to the Sunny Island falling
Physical injury (fractures or crushing) and damage to the Sunny Island.
• Ensure that the wall can carry the weight of the Sunny Island.
• If mounting onto a wooden wall with studs, ensure that the wall mounting bracket is firmly
connected with all studs.
